摘要:According to complicated occurrence environment such as high in-situ stress and strong seepage pressure, a true triaxial rock test system of coupled stress-seepage is developed, and its main structure, function and usage method are introduced in detail. This system could apply different three-dimensional(3D) stress values independently by servo control and real-time track the process of fissure propagation and evolution by acoustic detection system under 3D stress and seepage pressure. The influence of 3D stress and seepage pressure on permeability characteristics is studied through true triaxial rock test system on granite joint specimens with large size under different seepage pressures, and the test results better reveal the coupled stress-seepage characteristics of deep rock. The development of rock test system of coupled stress-seepage and test results enrich the method of studying rock mechanics properties under high in-situ stress and strong seepage pressure, and provide scientific experimental basis for research of stability and seepage disaster control technology of mining surrounding rock when meeting water.
